, Renewed October 4, 1933 Claims. (Cl. 282-21) This invention relates toa functionally and structurally improved inscribing machine as well as amethod of feeding a record therethrough.

Specifically, it is an object of the invention 5 to provide aninscribing machine in the nature of an autcgraphic register which willembody relatively few parts each individually simple and rugged inconstruction, these parts operating over long periods or time withfreedom. from it mechanical difiiculties and with utmost efficiency evenin the hands of relatively inexperienced operators.

A further object of the invention is that of furnishing an apparatus ofthis character in which several record strips will be fed towards andthrough the inscribing station in an improved manner and without anydanger of the parts of the record moving out of alignment.

Another object is that of furnishing a register with which a record mayreadily be associated and in which the application of the record to thefeeding mechanism may 'be accomplished with minimum skill, time andeiiort.

With these and further objects in mind, reference is had to the attachedsheets of drawings illustrating one practical embodiment of theinvention, and in which Fig. l is a side elevation of the register;

Fig. 2 is a sectional side view thereof;

Fig. 3 is a plan view with certain of the parts broken away to discloseunderlying construction;

Fig. d is a transverse sectional view taken along the lines 4- and inthe direction of the arrows of Fig. lyand Y Fig. 5 is a fragmentary viewoi a record of the type which is employed in connection with theregister.

In these views, the numeral 10 indicates a base from which walls 11extend upwardly to provide to a casing for the reception of a record 12which is preferably fed over a guiding bar 13 and between separatingbars 14 and baffles 15. A plate 16 provides a. deck surface at theinscribing station of the machine, and the individual layers 46 of therecord after passing between the separating bars and baffles, move overthe deck, the inscribable portion of the record being framed within anopening forming a part of a plate 17, the latter providing suitable restand supporting so surfaces or areas. The plate 16 may be pivotaliysupported upon a bar 18 and cooperate with the rest portions 19extending from the inner faces of the side walls to prevent its movementbeyond a, predetermined point. The plate 17 is hinged as at 20 and inits position of rest bears against the upper edges of the side and/orend walls and may be retained against accidental displacement by virtueof a catch of any desired construction,

but which, in the embodiment under consideraas interleaved-carbonsbetween the strips. While such a construction might be resorted to atthe option of the manufacturer, it will be observed that as shown, thecasing has an extended portion 24 within which there is housed a roll ofcarbon strips which latter are extended between the layers of the recordso that inscriptions upon the upper surface of the uppermost recordstrip will at the time of their impression be duplicated upon, forexample, the upper faces of the underlying inscription receiving strips.At this time, it will additionally be understood that any desired meansfor feeding the carbon strips might be resorted to, or in fact, that anyform of record suitable for this purpose might be associated with theregister.

Now with a view to providing a mechanism which will serve not alone toaccurately feed the record through the register but will additionallyserve to preserve proper registry between the several record layers, itwill be noted that an operating shaft 25 extends between the side wallswhich rotatably support it. This shaft might be moved in any desiredmanner but is preferably turned by a crank 26. A gear 27 moves with theshaft and meshes with the teeth of the gear 28 carried by a shaft 29.The latter is supported in spring pressed bearings 30 and these areassociated with a casing 31 pivotally mounted for swinging movement byarms 32 which latter have their inner ends pivotally secured to the sidewalls of the casing. Spring pressed catch members 33 normally retain thecasing in such a position that the teeth of the gear 28 mesh with thoseof the gear 27 and thus as the shaft turns, the shaft 29 will rotatecarrying with it a roll 34, the purpose of which will be hereinafterbrought out.

The gear 27 serves the additional purpose of preventing movement inother than a forward direction by the shaft 25 in that a pawl 35 cooperating with the teeth of this gear prevents rearward movement.Additionally, it is preferred that a spring pressed pin 36 extends fromthe side wall of the casing and in the path of travel of the crank armsothat after each rotation of the latter, it is necessary to retract thepin before a further rotation may be effected.

It is intended that a single rotation of the shaft shall cause thefeeding of the record to move the distance of one form of sheet stack.To this end, the circumference of the gear 27 is such that his in excessof the length of one form. Moreover, a feeding disk 37 is attached tothe shaft 25 and rotates with the same, this disk also having acircumference which is greater than the length of one record form leafwhich is the distance between two successive fold lines of the record.This disk is extended in the form of a record contact portion 38 whichapproaches its uppermost position as the crank moves into contact withthe stop pin 36. At the forward end of this contact portion, a springpressed pin 39 is carried by the disk, this pin being projectable beyondthe periphery of the disk so as to be engageable with the side edges ofthe apertures 40 which form a part of each record set. Actuation of thepin occurs as for example by associating with the shaft 25 a cam member41, a face elevation of which is shown in Fig. 2. The cam member isshown in the form of a disk, having formed in its face an internaleccentric cam surface or groove 41' having a stepped or shoulderpart-42'. The inner end of the pin 39 is offset as at 42 to ride underthe influence of the spring in contact with the cam surface. This cam isrestrained against movement as for example by an arm 43 extending intocontact with the bar which carries the pawl 35 and as a. conseqence,when the shaft 25 rotates, the cam remains stationary and the offset endportion of the pin 39 rides in contact with the cam surface,Accordingly, the operation of the pin 39 from the position as shown inFig. 2 will be as follows: The pin will be in contact with the edges ofthe apertures 40 of the record, and in moving forward with the disk 37under the rotation of the shaft 25 will gradually-due to its divergenttravel with respect to the path of record travel-be withdrawn from theapertures of the record. Thereafter, the pin will be retracted by theeccentric cam surface to extend substantially flush with the outersurface of the extended portion 38 and will ride in this condition to apoint underneath the, record when just as the crank moves into contactwith the pin 36, the shoulder portion 42 of the cam 41 will be traversedby the offset end 42 of the pin 39 and the latter under the influence ofthe spring will again be projected through the apertures of the nextsucceeding record set.

During the afore described movement of the parts, it will be understoodthat due to thecontact between the roll 34 and the upper surface of therecord as well as the engagement which will occur between the peripheryof the disk 37 and the record, the latter will move forwardly and due tothe circumference of the disk as well as that of the gear 27 (as aforebrought out) a complete rotation will result in a feeding of the recordof the record for one set of leaves or sheets. Obviously, the enlargedportion 38 will serve to assure the initiation of movement of the recordas the shaft turns, this being further assured due to the positiveengagement of the pin39 with the record apertures, it being understoodthat the pin however serves the additional purpose in co operation withthe apertures of assuring a perfect registering of the successive recordpiles.

Reviewing briefly the operation of the parts, the operator afterswinging the plates 1716 upwardly, disposes a record packet within thecompartment appearing in Fig. 2. The strips of this record are passedover the rod 13 and between the separating baffles '15. Thereupon, theplate 16 is swung downwardly and conceding that carbon is employed, thestrips of the latter are interleaved between the record strips. Theaperture of the first set of records is brought into engagement with thepin 39 and the plate 17 as well as the casing 31 are now swungdownwardly and secured in position. Thereupon, the upper record surfaceis suitably inscribed and by simply rotating the shaft 25 afterretracting the stop pin 36, the record is fed forwardly to a pointbeyond the inscribirig station andat which the inscribed record pile maybe severed from the record. Despite the fact that according to thepresent invention, only a single aperture is necessary in each recordset and to this end only one feeding unit is provided as part of theregister, it will be found that the record will feed forwardly withoutany danger of the record tending to move obliquely. This is thecasedespite the fact that the feeding mechanism and apertures arepreferably, although not necessarily, to one side of the center line ofthe record. In this connection, it will bev observed that the correctfeeding of the record is promoted and assured by virtue of the positivedriving connection between the shaft 25 and the feed roll 34 such as theintermeshing tooth gears 27, 28. By means of this driving connection,there is a very positive and effective feeding effort upon the recordbecause both the feeding disk 37 and the feed roll 34 are positivelydriven in synchronism. It will be found in connection with such .110feeding that the several parts of the record will move forward as a unitand this movement will continue until such'time as the record pile hasbeen shifted entirely beyond the inscribing' station. At that time, thefeed arresting and strip 115 registering aperture of the next succeedingpile will move to a .point at which the periphery of the disk extendsinto the same. Of course, due

to the fact that the lower strip of the record has a lesser distance totravel than the super--12!) posed strips, it is obvious that anytendency of the record parts to move out of alignment will be correctedfor the reason that the disk edge will now contact through the apertureof the lower strip with the under face of the second strip and 125 shiftthe same into perfect registry. Thereupon,

the disk will, of course, perform no further useful function unlessstrips above these strips'are also out of alignment. In this case, thesestrips will .be successively brought into registration and the 13movement of the disk will continue until the crank engages the stop pinor the shaft is otherwise brought to a stop. -Of course, thisregistration of the parts is further assured incident to the feedingoccurring due to the contact between the'135 roller and the upper faceof the record. Thereupon, the entire operation may again berepeated.

Thus, among others, the several objectsof the invention as afore broughtout have been achieved.

It will be understood that numerous changes in ea set pin forming a partof said unit and to he extended through the feed arresting apertures ofsaid record to initiate movement of the latter, and pin operatingconnections for automatically, periodically retracing the pin byoperation of said unit.
